To in current trace points；
After A3, stop recording, each tracing point is linked in sequence into original route according to time order and function；
A4, the original route is entered after edlin to preserve, form wheelpath.
Preferably, the step A4 includes：
Unnecessary loop, merges the too small tracing point of spacing in A41, elimination original route；
A42, the displayable map route of generation, map route is completely included on map, shows all of route letter
Breath；
A43, on map tracing point position be adjusted, merged, according to the corresponding prompt message of route information editor
And preserve；
A44, it is that the original route sets applicable vehicle and weather conditions, the original route after editor is saved as into row
Wheel paths.
Preferably, the positional information is：The longitude and latitude of present position.
Preferably, the scheduled duration is 10 seconds.
Preferably, the route information includes：
Important direction information, the unsafe condition that should be noted, the road conditions that should be noted and treatment advice.
Preferably, can also be further included before the step C：
User selects departure place, destination, departure time and vehicle by client.
Preferably, the server can inquire about the weather conditions by weather api interface.
As above it is visible, in the present invention can offline in the digital map navigation method of field driving, due to can due to client
Wheelpath is formed with according to actual traffic route, and record the various route informations in traffic route, then will be formed
Wheelpath uploads onto the server, therefore when other users need, you can request message is sent by user end to server,
Server can be inquired about and the client where selecting a suitable wheelpath to return to user according to request message so that
Client can according to return wheelpath perform digital map navigation, such that it is able in the wild or other without basis road equipments
When the region of information travels, safely and effectively navigation Service is provided the user, there is provided the available traffic route of safety.
Brief description of the drawings
Fig. 1 be the embodiment of the present invention in can offline field drive a vehicle digital map navigation method schematic flow sheet.
Specific embodiment
To make the objects, technical solutions and advantages of the present invention become more apparent, develop simultaneously embodiment referring to the drawings, right
The present invention is further described.
Present embodiments provide it is a kind of can offline field driving digital map navigation method.
Fig. 1 be the embodiment of the present invention in can offline field drive a vehicle digital map navigation method schematic flow sheet.Such as Fig. 1 institutes
Show, in the embodiment of the present invention can offline field driving digital map navigation method mainly include：.
Step 11, forms wheelpath, and record the various route informations in traffic route according to actual traffic route.
In the inventive solutions, it is possible to use various implementations realize above-mentioned step 11.Below will be with
As a example by a kind of implementation method therein, technical scheme is introduced.
For example, preferably, in one particular embodiment of the present invention, the step 11 can include：
